Hiya, my friend is to cocky to ask.. lol does his car have drum or disc brakes on his 1998 Saturn SL2, and if so how hard would it be to change to disc?

I can't tell from here
You can look under the car inside the rear wheels to see if there are rear disc's there or drums. The front brakes are disc's for sure. You can swap the rear drums for disc's. SPS has a kit with all the parts needed http://www.spswebpage.com/store/inde...5196a761eb16c5
